Cannot build sdk 17.1.0 examples/dfu/secure_bootloader b/c missing uECC.h file (not in SDK folder)

[ms360]

Hi 

I tried to find this file in the SDK folder and it does not exist. 
I do have it enabled in the stock sdk_config.h

mike@slavebox armgcc % find /Applications/nRF5_SDK_17.1.0 | grep uECC

mike@slavebox armgcc %

I saw some related posts but it looks like its an include path issue for them. 

Thanks!
